. A seat '18; is provided As illustrated in Fig. 6, radiator conneo-:: tion 6 is adapted to thread into an openin provided in an enlarged portion 20 fOIIlle" on the casing 7 at opening, the casing 7 is provided with an integral wall 21 which divides this opening into two distinct passages 22 and 23. Radiator connection 6 is provided with a parti-- a manner to permit the resulting passages 25 and 26 to cooperate with the passages 22 and 23. The integral wall 21 is flared outwardly at each side, as indi cated at 27, so as to increase its engaging surface with the valve gate 11. I prefer that the width of than the'width of the radial slots 10, so that at no time will the passages 22 and 23 be in communication with each other as the result of the integra wall not being covered bythe valve gate. Diametrically gate 11 may -close 23 from communi- Passa es 22 and y bulging ofi" the passages 22 and 23 are formed in the casing?.

see Fig. 4'... w 'valve will. now-be The 0 erationofithe described: If the this sgrface be greater one side. Adjacent this opposite the integral wall 21 the casing 7 is likewise flared outwardly at, 28 so that the valve 3 registration the radiator (not shown) the gate valve is In ved downwardly against the seat 18'. Th s puts passage 25 in the radiator connection 6 in communication with the passage 15 in the pipe connection 4. The flow" ascending in'the passage 15 by virtue of the extending baffle 12 in the T 2, passes through a'certain number of the vertical openings 19 in the gate valve 18. From these openings 19 the flew passes radially outwardly into the passage 22 which is in communication with the passage 25'. Upon returning from the radiator the flow enters the valve by way of the passages 26 and 23, passing through the remaining slots 18. and 19 and returning through the passage 16 to the heat supply line 3.

"It will, therefore, be noted that the supply line and return pipe may be one and the samepipe, and that but one .valve may be required to control the flow when entering and when leaving the radiator. To shut off the radiator, the gate valve is moved upwardly so as to bring the slots 18 out of with the passages 22 and 23. This allows the flow ascending in the passage 15 to enter the space below the valve gate in the casing 7 and return downwardly through the passage 16 into the heat supply line 3.

By this arrangement, steam, hot water, or whatever heat fluid that is employed, can not enter the radiator but may continuously flow through the pipe connection, and will be returned immediately into the supply line by the passage 16.

It will be noted that thecirculation through the valve will be assisted by a suction pressure forming directly behind'the ballle plate 12 and tending to draw the fluid downwardly out of the passage 16.
